Definitions

  • the invention relates to a silencer for pressurized exhaust gas, which is in particular exhaust gas from a suction gripper, e.g. Compressed air and intake air, and in particular a suction gripper with the silencer or a method for damping the sound, which is released into the environment when releasing pressurized exhaust gas.
  • the exhaust gas preferably has a temperature of up to 70 ° C, e.g. 0 to 50 ° C.
  • the EP 2415696 B1 describes a suction gripper with a central tube, which sucks in air under the supply of compressed air to a first end and lets it escape through an opposite second opening, wherein a line or a housing can be arranged adjacent to the second opening for sound absorption.
  • the US 2,893,434 A describes a vibration damper for a hydraulic system, which has a circumferentially closed elastic hose in a housing, the inner volume of which can be connected at one end to the hydraulic system.
  • the internal volume or the internal cross section of the elastic hose can be changed by turning one of its ends towards the other end or by loading it with a roller that can be moved along the hose.
  • the DE 2 238 657 A describes a muffler for high-voltage gas pressure switches with an expansion space through which the compressed gas is led outside, the wall of the expansion space being at least partially designed as a rubber-elastic membrane that is provided with pores that open when a dynamic pressure occurs and through which only the compressed gas can flow out of the expansion space.
  • the object of the invention is to provide a muffler and a method for sound damping for exhaust gas under pressure which is emitted to the environment.
  • a preferred task is to provide a silencer and a method for silencing a suction pad.
  • the muffler should have a simple structure and be easy to disassemble and then assemble, for example for cleaning in a dishwasher.
  • the invention solves the problem with the features of the independent claims, in particular by a silencer and a method for silencing with the silencer, which has a housing with an inlet for connection to the exhaust pipe of a suction pad, the housing having at least one elastic section with at least one Has breakthrough.
  • the elastic section closes the housing at a distance from the inlet, the at least one opening forming the outlet of the housing.
  • the housing therefore has an inlet for connection to the exhaust pipe of a suction gripper and at least one outlet which is formed by at least one opening in the elastic section.
  • the elastic section has an elasticity which, when exposed to pressurized exhaust gas, allows the opening to expand and enlarge to an opening which is larger than the opening of the opening without the pressurized exhaust gas being applied.
  • the at least one elastic section covers openings of the housing, which the housing has in addition to at least one inlet for exhaust gas or for connection to an exhaust pipe.
  • the elastic section can e.g. form a section of the wall of the housing, only the at least one opening in the elastic section forming the outlet of the housing.
  • the elastic section can be fastened directly to the housing or in an element which has at least two openings, each of which is closed by an elastic section.
  • the elastic section can consist of elastic material and cover at least one opening of the housing, the elastic section being held, for example, by means of a frame which is arranged on the housing.
  • the elastic section can be held in sections or completely displaceably on the housing.
  • At least one opening in at least one elastic section of the element leads to an effective damping of the sound that is released into the environment with the exhaust gas of a suction pad.
  • Pressurizing the elastic section with exhaust gas under pressure leads to its expansion and to the enlargement of the opening of the opening. It is currently believed that the elongation and / or the elasticity of the elastic section in which the opening is arranged and the guidance of the exhaust gas through the open opening in the elastic section reduces the sound carried off by the exhaust gas.
  • the tubular elastic section has an elasticity which, when acted upon by pressurized exhaust gas, allows the opening to be deformed to a substantially larger opening than without being acted upon by the pressurized exhaust gas, e.g. an elasticity that a deformation of the outer diameter of the tubular elastic section by the pressurized exhaust gas to at least 101%, at least 102%, at least 103%, at least 104%, at least 105%, preferably up to at least 120% of the outer diameter in the non-exhaust gas Condition.

  • the tubular elastic section can have such elasticity that its opening in the state exposed to exhaust gas has an opening, the opposite edges of which are at least 0.01 mm, at least 0.1 mm, at least 0.2 mm or at least 0.5 mm, or are at least 1 mm further apart than in the non-exhausted state.
  • the at least one opening in the elastic section can have edges lying against one another without being acted upon by pressurized exhaust gas and can be formed, for example, in the form of at least one slot in the elastic section. Openings formed as a slot in an elastic section can be arranged vertically or at an angle different therefrom, for example from 30 to 90 ° to the surface of the elastic section, in a straight line or in a curved manner, spaced apart from one another and / or intersecting or overlapping. When the elastic section is stretched, such slot-like openings form openings through which the exhaust gas is under pressure, through which openings the exhaust gas exits, the sound carried off by the exhaust gas being significantly reduced.
  • Slit-shaped openings can be formed, for example, as cuts crossing the elastic section, through which essentially no material of the elastic section is separated out or in which the material of the elastic section is completely preserved.
  • the muffler preferably has slot-shaped rectilinear and / or at least sectionally curved and / or sectionally mutually arranged openings, the edges of which lie against one another without being acted upon by exhaust gas under pressure, the openings not crossing.
  • the elastic section preferably has a uniform thickness, e.g. from 0.5 to 8 mm, preferably 1 to 3 mm.
  • the elastic section has a small thickness immediately adjacent to the opening, e.g. in a range of 1 to 3 mm from the edge of the opening.
  • a smaller thickness adjacent to the opening can e.g. from 30 to 70% of the thickness of the elastic portion, e.g. run out into an edge which delimits the opening, which has the smaller thickness and e.g. form one or two opposing sealing lips around the opening.
  • Adjacent to the opening, the elastic section can e.g. taper towards the edges of the opening.

  • a tubular elastic section which has a plurality of openings distributed over the circumference, e.g. in the form of incisions approximately parallel to the longitudinal axis, it is preferred that at least one of its ends is slidably supported with respect to the housing in order to facilitate a barrel-shaped expansion when the exhaust gas is under pressure, in which the openings extend to outlet openings.
  • One end of a tubular elastic section can be held by fastening only one of its ends to the housing, the other end being closed and being movable at least in the direction of the longitudinal axis of the tubular elastic element, or by slidably holding or guiding the other end or both Ends on housing.

  • the limiter is preferably stretchable.
  • the limiter serves to limit the deformation of the elastic section under the pressure of the exhaust gas, so that the maximum opening of the opening is limited. It has been shown that a limiter, in particular made of elastic material, leads to a further reduction in the sound emerging with the exhaust gas.
